Variation simulation and diagnosis considering in-plane/out-of-plane welding distortion
International Journal of Naval Architecture and Ocean Engineering, 2019 Geometric variation including welding distortion accumulates as many parts are joined together, ultimately affecting the final product. This variation is then subjected to correction, which requires considerable effort, time, and cost. This variation can
